Two limitations were found regarding
the applicability of the SROM to subject
populations. First, although the SROM is
applicable to grade-school subjects, the
present results did not provide a specification
of the lower limit of valid and reliable
usage by grade. The SROM would seem to
be usable at least as early as the ninth grade,
since its concurrent validity at this grade is
good and since its test-retest reliability is
good at an even younger grade (the seventh
grade)
